A question must here be considered by way of supplement. Some men too much given to subtilty, while they admit that we obtain salvation through Christ, will not hear of the name of merit, by which they imagine that the grace of God is obscured; and therefore insist that Christ was only the instrument or minister, not the author or leader, or prince of life, as he is designated by Peter (Acts 3:15). I admit that were Christ opposed simply, and by himself, to the justice of God, there could be no room for merit, because there cannot be found in man a worth which could make God a debtor; nay, as Augustine says most truly, 269 "The Saviour, the man Christ Jesus, is himself the brightest illustration of predestination and grace: his character as such was not procured by any antecedent merit of works or faith in his human nature. Tell me, I pray, how that man, when assumed into unity of person by the Word, co-eternal with the Father, as the only begotten Son at God, could merit this."--"Let the very fountain of grace, therefore, appear in our head, whence, according to the measure of each, it is diffused through all his members. Every man, from the commencement of his faith, becomes a Christian, by the same grace by which that man from his formation became Christ." Again, in another passage, "There is not a more striking example of predestination than the mediator himself. He who made him (without any antecedent merit in his will) of the seed of David a righteous man never to be unrighteous, also converts those who are members of his head from unrighteous into righteous" and so forth. Therefore when we treat of the merit of Christ, we do not place the beginning in him, but we ascend to the ordination of God as the primary cause, because of his mere good pleasure he appointed a Mediator to purchase salvation for us. Hence the merit of Christ is inconsiderately opposed to the mercy of God. It is a well known rule, that principal and accessory are not incompatible, and therefore there is nothing to prevent the justification of man from being the gratuitous result of the mere mercy of God, and, at the same time, to prevent the merit of Christ from intervening in subordination to this mercy. The free favour of God is as fitly opposed to our works as is the obedience of Christ, both in their order: for Christ could not merit anything save by the good pleasure of God, but only inasmuch as he was destined to appease the wrath of God by his sacrifice, and wipe away our transgressions by his obedience: in one word, since the merit of Christ depends entirely on the grace of God (which provided this mode of salvation for us), the latter is no less appropriately opposed to all righteousness of men than is the former.
